IMPROVEMENT IN MARKER. FOR CARPENTERS.

The Schedule referred to in these Letters Patent and. making part of thesame.

To all whom it may concmz Be it'known that-I, G. M. NICKASON, ofEllenville, in thecounty of Ulster, and State of New York, have inventeda new and improved Marker for Carpenters, Joiners, 8m; and I do herebydeclare that the following is a full, clear, and exactdescriptionthereof, which will enable others skilled in the, art to makeand use the same, reference being bad to the accompanying drawing,forming part of this specification, in which- 'Figurel-rcpresentsa sideview, partly in section,

Figure 2 is a vertical transverse section of the same, taken on theplane of the line :v-a:, fig. 1.

Figure 3 is a detail frontview, on a small scale, showing the markerapplied to a machine.

.Similar letters of reference indicate corresponding parts.

This invention relates to a new device for marking the places onwindow-blinds, sashes, 860., where mortises are to be cut, and has forits object 'tornake such marking with snch'precision andaccuracy, that alarge number of bars or planks can be prepared alike, when to be usedfor a number of equal-sized shutters, sashes, or other. articles. i

The invention consists in the application and arrangement of aserieslongitudinally and horizontally, as as well as transversely-adjustablecutters or marking tools, fitted upon a bar, to which slight rocking.reciprocatiug, or rotary motion is imparted. V

A, in the drawing, reprcse'ntsa cylindrical or othershapedjnetal' bar,which has a groove or n'b parallel with its axis, and on which a seriesof sliding sleeves, B B, is fitted. These sleevesv can all be adjustedin any desired position on the bar by means of set-screws a, that Iprefer to fit with their of the bar, as in fig. 1.

ends into the groove Each sleeve has on one side a'projecting block, b,

which has a recess on the side toreceive the markingtool C.-

Tbis tool is slotted, as in fig. 2, and is fastened to the block bymeans of a screw, 0. When worn, it can be moved further out, to projectthe requisite distance from the bar A.

The cutting-edges of the tools-O areronnded'and sharpened, as shown.

The sleeves can, as aforesaid, be adjusted any snitable distance apart,and the tools can therefore beset to mark moitises of suitable width, atsuitable places.

One sleeve may even be arranged to hold two tools, as in fig. 1, inwhich case I preferto apply small washers, d, between one or both ofsaid tools and the block b, so that, according to the thickness of saidwashers, the tools can be adjusted apart on the sleeve.

The ends of the bar A are hung horizontally or vertically, in a suitableframe. The bar can then, by suitable mechanism, be rotated, oscillated,or moved up and down, so that it will, when a bar or plank is heldagainst it, mark the same with its tools for the required moxtises.

Thus, a large quantity of material can be accurately marked, and allpieces alike, after the tools have once been adjusted inthe bar.

Having thus described my invention,

What I claim as new, and desire to secure by Let ters' Patent, is-

The improved blind and sash-marker herein described, its several partsbeing each constructed and arranged with reference to the others, asshown and described.
